Both surface water and groundwater sources contain a lot of impurities. There are many coarse impurities in the surface water source, but they have been removed during the water intake process, so the feed water purifying treatment generally refers to the removal of those fine impurities.
The fine impurities in the raw water are mainly dissolved salts, suspended impurities and colloidal particles in water. In general, the amount of suspended solids in the surface water is higher, and the dissolved salt content in the groundwater is higher. The salt content of brackish water and sea water is even higher.
Among physicochemical methods, chemical precipitation, ion exchange, reverse osmosis, chemical oxidation, and activated carbon adsorption are methods for removing dissolved substances in water. Coagulation precipitation and filtration are methods for removing colloids and larger particles.
